Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 23 m/s at an angle 28 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. What is the horizontal component of the ball’s velocity right before Sarah catches it? What is the vertical component of the ball’s velocity right before Sarah catches it? What is the time the ball...

Playing shortstop, you pick up a ground ball and throw it to
second base. The ball is thrown horizontally, with a speed of 26
m/s, directly toward point A (Figure 4-16). When the ball reaches
the second baseman 0.40 s later, it is caught at point B. (Neglect
air resistance.) Figure 4-16
(a) How far were you from the second baseman? m
(b) What is the distance of vertical drop, AB? m
